GAIA was made
entirely with a propietary program, running on a standard PC,
for creating series of images based on the evolution and mutation
of image-generation algorithms. At each iteration, the user chooses
one of the proposed images, which acts as the progenitor of a
new series, and so on. The procedure is inspired by the evolution
of life. Following a "genetic code," the forms are born,
reproduce, and die, but instead of "survival of the fittest"
the rule is "selection of the most attractive."
